| Video resolution | Record the native sensor and encoded stream resolution. Full HD is 1920 × 1080 pixels; higher resolution alone does not guarantee better identification. | Check the product specification and inspect a captured stream at its configured settings. | Not assessed |
| Frame rate and motion | Confirm the supported frame rate at the selected resolution. As an evaluation target, test for stable 25 or 30 frames per second where the network and device support it. | Measure frame delivery during a live call and review motion in recorded clips under normal network load. | Not assessed |
| Low-light performance | Evaluate face visibility, exposure, noise, and any infrared illumination in dim conditions. No single lux figure is comparable without a defined test setup. | Test at documented illuminance levels and distances; compare recorded images using the same scene and settings. | Not assessed |
| Field of view and image coverage | Check horizontal and vertical viewing angles and whether the camera shows the approach area without excessive distortion or blind spots. | Verify the lens specification and test framing at the intended mounting height and entrance distance. | Not assessed |
| Two-way audio | Assess speech intelligibility, loudspeaker volume, microphone pickup, and delay in both directions. Supported audio codecs may include G.711 or G.722; codec support should be confirmed for the specific model. | Conduct calls at realistic distances in quiet and noisy conditions; check for clipping, echo, dropouts, and excessive latency. | Not assessed |
| Echo and noise handling | Determine whether acoustic echo cancellation and noise reduction are provided and whether they preserve natural speech during simultaneous talk and listen. | Test hands-free calls with the indoor station at typical volume and with representative background noise. | Not assessed |
| Call setup and reliability | Check call initiation, answer, timeout, missed-call handling, and recovery after a network interruption. SIP interoperability, when claimed, should be verified against the relevant implementation details; SIP is specified in RFC 3261. | Run repeated calls across the intended network and test the documented call flows and supported endpoints. | Not assessed |
| Unlock and relay control | Confirm relay type, contact rating, unlock duration settings, and fail-safe or fail-secure behavior with the selected lock. Compatibility depends on the lock and wiring design. | Review wiring diagrams and relay ratings; test the complete door circuit with a qualified installer. | Not assessed |
| Credential and reader support | Document supported credential types and interfaces. Wiegand 26-bit and 34-bit formats are common legacy options; OSDP is a standardized reader-to-controller communication protocol. Actual support is model-specific. | Verify the exact interface and credential formats in product documentation, then test with the intended reader and controller. | Not assessed |
| Power and network | Confirm the required supply and Ethernet options. IEEE 802.3af PoE specifies up to 15.4 W at the power-sourcing equipment; IEEE 802.3at specifies up to 30 W. Device power needs must be checked separately. | Check the device’s power budget, cable run, switch or injector compatibility, and behavior during peak operation. | Not assessed |
| Outdoor protection | Look for an IP rating tested under IEC 60529 and, where impact resistance matters, an IK rating under IEC 62262. The required rating depends on exposure and installation location. | Check the rating on official documentation and confirm that the rating applies to the installed configuration and accessories. | Not assessed |
| Security and privacy | Review authentication, user permissions, firmware updates, data retention, and encryption in transit. Confirm supported secure transport and configuration options rather than assuming they are enabled by default. | Inspect security documentation and settings; verify update policy, access controls, and network behavior before deployment. | Not assessed |
| Integration and support | Assess documented interfaces, integration requirements, firmware lifecycle information, warranty terms, and availability of installation and troubleshooting resources. | Request current documentation and support terms; validate any claimed integrations with the intended system before purchase. | Not assessed |
